-To zul-wm z'tmg/ concern: f .Be it known that LfiViLnini'i 1V. Roanni-*ILma citizen of the United States, resid` .ing atNewYorkcit ,in the county' of New a York and State of l\ew York, 4have invented certain new and useful Im roveinents in' Suction-Cleaners^ fully described and represented inthe ollowing specification and the accompanying drawings, forming apart tu ofthe sameff" This appplication relates to suction clean? ers ofthe self-contained type, that is, those iii-which a motor, fan, suction nozzle and Jdirt receptacle are mounted vto move to-- i5 gether las the I suction lorI cleanin nozzle is niove'd over the surface to be c eaned. 'It

is desirable' that cleaners of this kind, in'

- a. Vhose or tube leading stromahand tool` :vhichshall be of such character as to avoid vcomplications of` parts and-to` secure e'iiiao' ciency in operationby providing a directv `and-unobstru' cted path 'for the sucked-in air. The' invention relates especially tothe construction ofthe nozzle 4or, nozzle casing ex lforward and downwardvrom the ndersta ding of the invention can jven by a detailed descriptioifof bestlbe. an approy'ed embodiment of the-same, and

au nectionl with the "accompanying drawings;

erring tothe drawing, represents i a-.rota-ry suction fan mountedto rotate in the 'ancasing 11, the fan being mounte on and' driven by the', shaft 120i van elec- 56 tric motor 13 which is mounted ina. sup

portin casing l@ extending rearwardly from t ean casing; The front wallof'the fancasinigis formed with a central open'- to it a forwardlyand ticu ar construction shown the nozzle 16 rests directly on the floor or `f-fthe fan casing of, the machine.`

and which is Ta apted to pivot away from the iii-take openin to al position as indicated -by dotted lines. v:When

such a description will now be given in cond ,ing of walls, furniture, drapery, etc.

vthe cleaner is thus used with "a attached, the,elongated in-take openmgat downwardly extending nozzle casing providingia-n in-take passage, and the lower end of which is shaped to form -a oorc1eaning nozzle 16. The lower art of the nozzle casing is extendedlateral y or transversely of the machine as usual'to provide a comparatively long and narrow suction in-'take slot between the lips of the-nozzle. A. ldischarge passage 17 leads tangentially from the fan chamber and communicates through a backwardly leading pipe 18 with a po-` rous receptacle 1.9 for receiving the dirtand dust discharged from the fan chamber. The

receptacle 19 is hun from an operatin handle rod 20 which is pivotally connected to the body of the cleaner to swingverti- `cally Jand by -ywhich the cleaner 'is moved over the tloor'or surface to be cleaned. The cleaner is provided with a -pair of running wheels 21 of which one -is shown in the drawing, located to the rear of the center of avity of the cleaner, and in theparby the drawing floor overing, so thatthe cleaner is supporte by the running wheels 21 and the nozzleg A In addition to the elongated in-take slot or opening at vthe nozzle casing is ormed with a secondary normally closed in-take opening 25 located in the front wall of thenozzle case iig, such opening 2 5 being normally a by means vor the shutter 26 formed by a late which is pivotally securedat--the omt 27 and whi h when in its normal close polsition rests closely against the portions of the nozzle casin surrounding the opening, be turned'on its the shutteiis thus turned to open osition, the in-take openin 25 is adapte to receive, as indicated y dotted line s,va suitable connecting fitting on the end of4 a tilb leading from a hand nozzle or brush such as is commonly employed for'suction cleanthe bottom of the nozzle willibe-Sufiicicntly f closed by allowing it to rest directly against the bbttom of the nozzle 16,-

he closed .by other' vsuitable means This secondary in-take opening is best locatedwith its-axis lying in or approximately m a vertical plane\extcndin the machine and longitudina A y of its direction of movement,. and in afmachine inv which the axis of the -fan shaft lies in a central vertical .plane' extending longitudinall of the direction of movement of the mac ine, as in the machine shownzthe axis of this in-take opening is mostdesirably lo-l cated in `or approximately in such lane. It is also desirable that the opening `lo cated slightly below the center of the open- Yilng into the fan casing, principally for .the

'purpose of avoiding chance intrusion of anything into contact 'with the fan blades when the opening is o en.

It will be observed t at the. Vmeanswhich I provide furthe connection of a hand tool to the suction cleaner is not onlyl simple and in other respects' suitable for the purposeand unobjectinable, but it has 'the important advantage of avoiding interference with the eiliciency of the cleaner in its use for floor cleaning, and also gives a maximum eiliciency in the .use of the cleaner with a hand tool connected to the secondary in-take opening. -In both cases there is au unobstructed and substantially -direct pas-k sage through the nozzle casing from the in-take opening to the fan chamber. It will be noted, further, that\-by reason of the location of the secondary in-take opening, when a flexible pipe or tube is connected therewith leadin to a hand tool the cleaner may be moved a t ut as required by simply drawing it about by means of the connecting tube, which pulls from the frgnt of the machine in the dlrection in which the wheels run and which tends to lift the nozzle and front end Yof the cleaner so that the cleaner,`

resting mostly on its wheels 21, is easily moved about as desired.

That is claimed is:

l; A self-contained suction cleaner having a nozzle casing extending forwardly and downwardly from they front wall of4 the yfan casing to provide an in-take passage communicating directly with the lfan chamber through a central opening` in the' front wall of the fan casing concentric with the fan axis, said nozzle casing being extended laterallyV at its lower end to form a door cleaninglr nozzle having an elongated in-take openinc, and said nozzle casing hav- 'lng Aa normallsy closed in-take opening in the wall above sald elongated in-take opening for connecting a tubg leading .from a. cleaning tool with the in-take. passage through the nozzle casing.
